Hi Chuck,
A good place to start are the help videos here
http://www.ddisoftware.com/qimage-u/learn.htmAlso accessible from the Help menu, which by the way, is still relevant to many features.
Where you see a little V in a Red circle in QU, there's a help video available.
I don't the latest UI with separate tabs is covered but there's enough in the videos to get you going, just not what there is in each of the tabs.
Which printer did you buy?
